4 Claims. (01. 20-50) This invention relates to window constructions,and is particularly directed to doublehung windows wherein theindividual window sashes are adapted to have both vertically slidingmovement in the window frame and inwardly swinging pivotal movementabout one edge of the sash.

The window of the invention is shown as being of the type wherein awindow sash is se.-. cured to a, window frame by means of a pair ofslides one of which is associated with the lat.- erally outer edge orvertically extending side of each window sash intermediate it and theadjacent part of the frame. Each sash is shown pivotally secured at onevertically extending edge to one slide and the remaining verticallyextend.- ing edge is releasably engaged with the slide associatedtherewith. In order to disengage a sash from its one releasable carrierslide, the slide normally is placed at or adjacent its upper extremityof movement, and retained in such position while the window sash isunlocked from enga m nt with such slide and moved downard y of theframeto be. completely released fr m en a ement with the carrier slide aftera predetermined len th .of relative movement has occurred betwe n theslide and the window sash.

One, type or ,a pivotal and slidable window similar to th general typereferred to is shown and described i my U- S- Paten- 2584.684, while ofthe class d scri ed which is characterized by the auto tic e c s ment ofa sl de member releasably with a portion of a window sash bypredetermined relative movement therebetween.

Anoth r object of th inv n i n i t provide a slide member for a, windowsash. w ich slide member connects in a novel and releasable mane ner toa window balance and to the window sash with which it is associated.

An ther object of th i v nt on is to provide a window construction ofthe character described that h s novel, sturdy. improved means for engain a slide m mber relcasably with a window sash.

A fu ther. o ject of the inv ntion is to secure av window balance memberquickly and easily and in a releasable manner to a slide member used tosecure a wind w s sh a window frame.

Still another object of the inventignis to provide a window of thecharacter described wherein a tree edge or .a window sash can only .bere v specification to facilitate reference 2 leased from its controlslide at a desired vertical point.

Another object of the invention is to provide a window of the classdescribed which is made from a minimum of metallic parts and which hasdesirable operative properties.

Yet another object of the invention is to provide an improved windowconstruction which is of sturdy construction and which is adapted tohave a long service life with a minimum of maintenance thereon.

The foregoing and other objects and advan-. tages of the invention willbe made more apparent as the specification proceeds.

For a better understanding of the invention, reference should be had tothe accompanying drawings, wherein Fig. 1 is an elevation of a windowconstruction embodying the principles of the invention;

Fig. 2 is an enlarged fragmentary vertical section of an upper cornerportion of a window of Fig. 1;

Fig. 3 is an enlarged vertical section taken on line 3-3 of Fig. 2;

Fig. 4 is an enlarged horizontal section of the windows of Fig. 1 online 4-4 of Fig. 1 with one window slid into overlapping relation withthe other;

Fi 5 is an enlarged fragmentary vertical section through the releasablelock means of the invention; a d

Fig. 6 is an enlarged elevation, partially broken away and shown insection, of the lower part of a Slide and its associated means.

The present invention relates to a double hung window construction andthe invention broadly comprises the combination of a window frame, apair of window sashes, slides engaging one edge of each window sas tothe frame, with slides or th oth r v ti s es each of the window sashes,means engr ing such last-named slides with the frame for slidingmovement, lock means releasably carried by the last-named slides andautomatically positionable by gravity for engaging the lower end .Qf thesash to engage same with the. frame, a window balance for each of thesashes, and means for securing oneofzthe window balances in a quicklyreleasable manner to the upper por io o each last-named slide tofacilitate securing or changing the balances in the window construction.

Corresponding numerals will be used to identify correspcnding parts inthe drawings and the t between such par 1s.

Reference now should be had to the details of the structure shown in thedrawings, and a window construction which is indicated in general by thenumeral l is shown and it includes a substantially conventional windowframe 2 that has a pair of double hung sashes 3 and 4 positioned thereinby means of a pair of slides 5 and 6, and i and 8, respectively, foreach of the window sashes 3 and 4.

Fig. 4 of the drawings best shows that each of the slides is providedwith a vertically extending dove-tail shape in section recess 9, ID, IIor !2, respectively for the slides 5 through 8, respectively. Suchrecesses 9 through l2 are engaged with suitable jamb run strips i3, l4,l5 and i6, respectively, in order to engage the slides 5 through 3 forvertical sliding movement on the frame 2. These slides 5 through 8 arereceived intermediate the laterally outward edges of the window sashes 3and l and the laterally inner surfaces of the window frame 2, asindicated in the drawing. Usually suitable hinges, or butts IS pivotallyengage the window sashes 3 and 4 with the slides 5 and l, as shown inFig. 1, so that such vertically extending edge of each of the windowsashes 3 and 3 is connected to the window frame for pivotal and slidingmovement with relation thereto by means of the slides 5 and I and thehinges I8. Of course, when desired, the type of a combined hinge andpivotal or runner strip as disclosed in my above-referred to copendingapplication can be used in place of the slides 5 and I and the hinges itfor pivotally connecting one edge of each of the window sashes pivotallyand slidably in the window frame.

One important feature of the present invention is that a plurality ofspring balances i9 are positioned at the upper portion of the frame 2and these balances l9 have balance tapes 26, 2|, 22 and 23 extendingresiliently therefrom for individual engagement with the slides 5through 8 to aid in positionin them in the window frame to aid invertical movement of the window sashes 3 and i. Fig. 3 shows that thebalance tape 2! like the other balance tapes of the invention, has atape end connector, or end portion 24 which is pivotally secured to thetape. Thus each of the slides 5 through 3 has an obliquely directed, oran upwardly and outwardly directed hole or other opening 25 providedtherein that extends completely through the slide from the inner to theouter surface thereof with relation to the lateral dimensions of thewindow of the invention. Such hole 25 is bisected or cut into twoportions by suitable means, such as a pin 26, that extends across thehole 25 intermediate the ends thereof. These pins 23 engage the slidesto be supported thereby.

Fig. 3 best shows that the end 24 of the balance tape 2| is doubled backaround the pin 26 so that the resilient positioning of the balance tapes23 through 23 urging them upwardly of the window l binds or wedges theend portion 24 in the holes 25 to secure the balance tapes releasably tothe slides 5 through 8. Such balance tapes can be readily engaged withthe slides since the laterally inner surface or edge of each of theslides 5 through 8 can readily be exposed by disengaging the windowsashes 3 and 4 therefrom so that the end portions 24 of the tapes can bepulled into the center portion of the frame 2 through the holes 25 afterwhich the tape ends 24 can be doubled back and the tapes be drawn backinto the holes 25 until the tape ends are properly posi-- tioned aroundthe pins 26. It further will be seen that at any desired time the tapeends 24 can be pulled laterally inwardly from the exposed end of thehole 25 by a small hook, or the tapes could be pushed inwardly withrelation to the slides from the top of the slides so that the tape endscan be straightened out, and the tapes be disengaged from the slideswith which they have heretofore been engaged. Fig. 4 shows that thebalance tapes 28 through 23 lie intermediate the jamb run strips and theadjacent laterally outer surface of each of the slides. Thus the balancetapes do not interfere with the operation of the window of the inventionin any manner and are snugly positioned in a substantially hidden mannerin the window construction.

Fig. 5 clearly shows another important element of the present inventionwhich is a releasable means for securing the free or the remainingvertical edge of each of the window sashes 3 and 4 to the slides 6 and 8to engage same slidably with the frame 2. Thus lock arms 21 and 28 areshown to be pivotally engaged with the slides 6 and 8, respectively, bythe pins 29 and 30, respectively. The lock arm 21 has a protruding lockfinger 3| that extends laterally inwardly of the window I and this lockfinger is doubled back upon itself out of a general plane defined by thelock arm 2'1. A rearwardly or outwardly extending locking lug 32 is alsosuitably formed on the lock arm 21 for a purpose to be hereinafterexplained. The lock arm 28 has a lock finger 33 provided thereon similarto the lock finger or section 3i of the lock arm 21. The constructionand arrangement of both look arms 21 and 28 is such that the lockfingers are normally positioned by gravity to extend laterally inwardlyfrom the remainder of the lock arm and will en gage the lower surface ofthe associated window sashes 3 and 4 when the slides B and 8 arelaterally aligned and otherwise engaged with the window sashes, asindicated in Fig. 5 of the draw- Fig. 5 shows that the jamb run strip 14has a suitable recess or kerf 34 cut therein at one vertical portionthereof for reception of the lug portion 32 of the lock arm 21 todisengage the lock arm and hence the slide 6 from locked engagement withthe sash 3. The kerf 34 usually is of a short or localized length sothat normally such lock arm 2'! cannot be pivotally'moved laterallyoutwardly with relation to the window sash 3 and thus normally willretain the slide 6 in engage ment with the window sash 3 until such sashis moved adjacent to its vertically uppermost position at which time thelug 32 can be swung into the kerf 34 and downward movement of the windowsash 3 while the slide 6 is held against movement will disengage samefrom the slide 6. After complete release from the slide 6, the windowsash 3 is free for pivotal movement about its re-' maining vertical edgeand the hinges 18 secured thereto.

Sometimes it may be desired tolock the lock arm 21 in inoperativeposition and hence a screw 35 or similar member is positioned in thekerf 34 so that a sharp edge portion is provided to engage with a littlenotch or similar recess 36 pro-- vided in the lower part of the lock arm21 for engagement with this screw 35 to maintain the lock arm 21 ininoperative position. Usually the slide 6 has a limited amount ofvertical movement left at the portion of its travel that the lug 32 isreceived in the kerf 34. Thus when engaging a window sash 3 with theslide 6 by upward move-. ment of. the sash, the sash can and will movethe- "slide 8 vertically a short distance to disengage the lock arm 21from the screw and permit an automatic gravity locking action orengagement between the slide and the window sash by the arm 21. Usuallya small shoulder or stop member 31 is provided on the laterally outeredge of the window sash 3 at the lower end thereof and suchfshou'lder3%! is adapted to engage the lower end of a runner 38 that usually isdove-tail shape section formed on the laterally inner fS liif'a'ce ofthe slide 6 'to'provide a positive in'terengagement of the slide 6 andthe window sash 3. The slide 8 usually has a}ruriner 38 thereon forsimilar engagement with the edge of the window sash 4, as indicated inFig. 4, and such runners +88 and 39 usually extend at least substantiav-th s ensth 0f thes1ide In some instances, it may be desirable to havea slightly different type of a release action between the slide 8 andthe 1ower window sash 4. Hence an elongate kerf is shown provided in thejamb run strip I6 with which the slide 8 engages. This kerf 40 isadapted to receive the rear portion of the lock arm 28 therein when sameis swung laterally outwardly about its pivot 30.

Accordingly, at any point in the movement of the lower window sash 4,the lock arm 28 can be swung outwardly into the kerf 40 to prepare thesash 4 and slide 8 for separation by disengaging the slide 8 from thewindow sash 4 by the required relative movement downwardly of the windowsash with relation to the slide. Of course, the balance tapes connectingto the slides of the invention will serve to draw such slides normallyto the upper portion of the frame 2 when disengaged from the windowsashes, or at least to hold the slides in a given position. The lowerwindow sash 4 has means on it, like the shoulder 37, for positivelyengaging the window sash 4 with the slide 8 when such window sash andslide are properly horizontally aligned by vertical upward movement ofthe window sash 4 with relation to the slides 8.

It will be appreciated that, when desired, the lock arms 21 and 28 maybe provided with suitable means for retaining them in inoperativeposition and they may be permitted only localized unlocking action. Ofcourse, any desired type of balance means may be used in the window ofthe invention. The construction shown, it will be noted, is particularlycharacterized by the minimum of metallic parts provided therein sincesubstantially all of the components of the window can be made from wood,if desired. Any suitable type of sealing means may be provided in anyportion of the window and frame means of the invention for sealing therelative components of the window construction with relation to eachother. The lock arms 27 and 28 usually are positioned in slots and 5|formed in thelower parts of the slides 6 and 8, respectively. Thelocking fingers of the lock arms 2'! and 28 are offset with relation togeneral planes defined by the body portions of the lock arms and thisenables the lock arms to engage the sashes 3 and 4 offset from therecessed parts of the sashes that engage the runners 38 and 39. Suchlower corners of the window sashes can be reinforced in any desiredmanner.

From the foregoing, it will be observed that a novel type of a, slidemember has been provided for coupling a window sash to a window frame sothat a window balance tape can be readily and easily engaged with ordisengaged from the slide andwith the slide being automaticallyengageable with the window sash at desired times, thus it is submittedthat the objects of the invention are achieved.

While one complete embodiment has been disclosed herein, it will beappreciated that incdifica tion 0f this particular embodiment of theinvention may be resorted to without departing from the scope of theinvention .as defined by the -a pended claims.
